Casino game with next round multipliers

ABSTRACT

A player plays a first round of a casino game. If the player achieves a winning outcome on the first round of play, the payouts for the next round of play of the casino game will be increased. The amount of the increase is based on the category of the winning outcome on the first round of play. Each subsequent round of play continues to have increased payouts if the player continues to achieve winning outcomes. When the player has a losing outcome, the payouts revert to the base level. An extra wager may be required from the player to activate this feature during the play of the casino game.

BACKGROUND OF THE INVENTION

This invention relates primarily to casino games, and more particularlyto casino games such as video poker, keno and slot machines. The presentinvention provides the player with multipliers on the next round of playdepending on the outcome of the previous round of play.

Conventional video draw poker is a single player game in which theplayer does not play against a dealer or other players, but rathermerely tries to achieve the highest possible ranking poker hand.

After an initial deal of five cards, the player is allowed to discardand replace unwanted cards with replacement cards. Electronic videopoker games use poker hand rankings to determine winning combinationsand a payout schedule is used to determine the amount awarded to theplayer for achieving a winning combination.

The conventional winning poker hand rankings that are used in videopoker in order from highest to lowest are: Royal Flush, Straight Flush,Four of a Kind, Full House, Flush, Straight, Three of a Kind, Two Pairand a Pair of Jacks or better. Any hand having less than a Pair of Jacksor better is a losing hand. These winning poker hand rankings are usedin the Jacks or Better draw poker format as well as many of the otherdraw poker formats.

Video poker as a draw poker game using the Jacks or Better draw pokerformat has been played in gaming casinos for many years. Variations ofvideo draw poker have evolved and include video draw poker using Jokersas wild cards and video draw poker using Deuces (or even Sevens) as wildcards. Another known variation of video draw poker is the Tens or Betterformat in which the lowest winning hand combination is a Pair of Tens.Most of the more recent modifications to video involve the use ofdifferent draw poker formats such as Bonus Poker, Double Bonus Poker,Double-Double Bonus Poker and even Triple Bonus Poker. Different drawpoker formats involve changes to the pay table and often involve usingdifferent poker hand rankings as winning hand combinations.

Multiple hand video poker games allow the player to play more than onehand of video poker at a time. U.S. Pat. No. 5,823,873 to Moody, thedisclosure of which is incorporated herein by reference, discloses amultiple hand poker game in which the player plays two or more hands ofvideo poker at a time. An initial starting hand is dealt, the playerdiscards unwanted cards and replacement cards are dealt for thediscarded cards. The poker hand ranking of the final cards is determinedand the player receives a payout for any winning card combinationachieved. Each hand of the multiple hand poker game is treated as aseparate pay line for payout purposes. However, each pay line uses thesame pay table for the purpose of determining the amount received by theplayer for winning hands.

U.S. Pat. No. 6,638,163 (Moody) discloses a stud poker game withconsecutive rounds of play. In either a single hand format or a multiplehand format, the play makes a wager to start the game. As long as theplayer continues to achieve winning outcomes, the play continues toreceive additional rounds of stud poker without having to make anyadditional wagers. No pay table multipliers are disclosed in this methodof play.

U.S. Pat. No. 6,149,521 (Sanduski) discloses randomly applying amultiplier to a pay line based on the value of a multiplier card.Sanduski discloses using only a single multiplier value for a singlehand of video poker. For example, when a player achieves aFour-of-a-Kind, the payout for this winning combination is multiplied bythe value of the kicker card in the poker hand. There is no carryovereffect of any multiplier in the Sanduski game to the next round of playof the game.

U.S. Pat. No. 7,247,092 (Jarvis et al.), the disclosure of which isincorporated herein by reference, discloses the use of one or moremultiplier cards added to a conventional deck of playing cards. Whenevera multiplier card appears during the play of a video poker game, thepayout for any winning combination that is achieved is multiplied by thevalue of the multiplier card. This Jarvis feature has beencommercialized in a game known as SUPER TIME PAY which is marketed byIGT of Reno, Nev. There is no carryover effect of any multiplier in theJarvis game to the next round of play of the game.

The Jarvis multiplier card feature has been applied to multiple handvideo poker. For example, in TRIPLE PLAY SUPER TIMES PAY all pay linesare eligible for the same multiplier value should a multiplier cardappear in the initial deal of the starting hand. There is no carryovereffect of any multiplier in the TRIPLE PLAY SUPER TIMES PAY game to thenext round of play of the game.

U.S. Pat. No. 6,612,927 (Slomiany et al.) discloses a multiple handpoker game using multipliers. The player wagers to play four hands ofvideo poker. The first hand is played at a 1× pay table. If the playerhas a winning outcome on the first hand, the player plays the secondhand at a 2× multiplier. If the player has a winning outcome on thesecond hand, the player plays the third hand at a 4× multiplier. If theplayer has a winning outcome on the third hand, the player plays thefourth hand at an 8× multiplier. The multipliers from hand to handalways remain in the same progression of 1×, 2×, 4× and 8×.

U.S. Pat. No. 6,569,013 (Taylor) discloses a poker game which usesvarying pay tables. As the player achieves a winning outcome on eachconsecutive round of play, the pay table changes for the next round ofplay. When the player achieves a losing outcome on a round of play, thepay table resets to the base pay table for the next round of play.

Slot machines also have one or more pay lines and for each pay line thathas been activated by making a wager thereon, a player receives a payoutwhenever a winning symbol combination that appears on an active payline.

U.S. Pat. No. 6,120,378 to Moody, the disclosure of which isincorporated herein by reference, discloses a multiple reel slot machinewith multiple pay lines. The player makes a wager for each pay line thatthe player wishes to have activated for a particular round of play. Themethod of the present invention may be practiced using the slot machinedisclosed in this '378 patent as well as other slot machines which havemultiple pay lines.

The present invention provides a method for applying multipliers on thenext round of play of a casino game based on the outcome of the previousround of play thereby adding a new and exciting wagering and winningfeature for the player. The method of the present invention can beapplied to draw poker games and to slot machines. Stud poker games andkeno games may also be modified to use the method of the presentinvention.

SUMMARY OF THE INVENTION

The video screen display 20 also has a “BET” location 32 that shows theamount of credits that have been wagered on a particular round of playand a “WIN” location 34 that shows the amount of credits won by theplayer on a particular round of play.

Each electronic video poker game is designed to be played by having oneor more poker hands displayed on a video screen to a player. These are“player's hand only” poker games in which the player does not playagainst a dealer's hand or against other players, but merely attempts toachieve a winning poker hand combination using the player's final cardsof the hand. Awards are made for winning final hand combinations basedon the amount wagered by the player and the payouts that are displayedin a pay table.

An initial deal of cards comprises the player's initial hand. Bymanipulating the buttons on the gaming device or by using conventionaltouch screen technology, the player selects which cards he wishes tohold in his hand and thus which cards he wishes to discard. Replacementcards are then displayed for the discarded cards and the outcome of theplay of the hand is determined. The resulting poker hand ranking of thefinal hand is then compared to a pay table to determine whether theplayer has a winning hand combination.

The method of the present invention will now be described. An initialhand is displayed to the player. The player is then allowed to discardany unwanted cards from the initial hand. Replacement cards for thediscarded cards are displayed which results in a final hand. If thefinal hand has a winning card combination, the awards that can be won bythe player on the next round of play are modified by an amountassociated with the poker hand category of the winning card combinationthat was achieved in the final hand in the first round of play.

After the player has inserted an appropriate amount of coins, tokens,currency or tickets to add a sufficient amount of credits on the creditdisplay meter 22, the player makes his initial wager. The player maypress the “BET ONE” button 42 one or more times to bet in singleincrements or the player may merely press the “BET MAX” button 44 andthe maximum number of credits are applied, for example, five credits arewagered on each of the three hands to be played and an additional fivecredits are wagered on each of the three hands to be played to activatethe multiplier feature. The player can also use the touch screenlocations to make his wager as described above.

As shown in FIG. 1, a player has made a thirty credit wager shown in the“BET” location 32. This activates three hands to be played HAND ONE 71,HAND TWO 72 and HAND THREE 73: five credits are allocated as the amountwagered on each hand and the additional five credits are required forthe multiplier feature on each hand. In the preferred embodiment of thepresent invention, a player must make an extra wager to be eligible forthe multiplier feature. The amount of the extra wager relates to thefrequency and amount of the multipliers applied to the various paylines. In a preferred embodiment of the present invention, the amount ofthe extra wager is equal to the amount of the wager made on a hand,although higher or lower amounts for the extra wager may be used.Alternatively, no extra wager could be required for the multiplierfeature, but the pay table would have to be adjusted for the increasedpayouts that would come from the multiplier feature.

In the present invention, the multiplier feature does not apply to thepresent round of play, but applies to the next round of play. The playeris making this wager on the present round of play to earn thepossibility of receiving multipliers on the next round of play. At anypoint during the play of the game, if the player does not make the extrawager for a particular round of play, then the next round of play willoccur at the base pay table having only a 1× multiplier.

Because FIG. 1 shows the initial first round of play, there is only a 1×multiplier on each hand. As shown in FIG. 1, a 1× multiplier 61 appliesfor HAND 71, a 1× multiplier 62 applies for HAND 72 and a 1× multiplier63 applies for HAND 73. The payouts for any winning card combinationsthat are achieved on each of these pay lines are paid according to theassociated pay table with only a 1× multiplier applied to those payouts.As discussed below, any multipliers that are earned during this firstround of play are applied to the pay table for the next round of play.

The poker game shown in FIG. 1 as an example is a three hand poker gameplayed in accordance with the method disclosed in U.S. Pat. No.5,873,823.

The player has been dealt a first HAND 71 of the Ace of Spades, Five ofHearts, Eight of Clubs, Ace of Hearts and Three of Diamonds. The playerhas selected to hold the Ace of Spades and the Ace of Hearts and thesetwo cards are duplicated into second HAND 72 and third HAND 73.

As shown in FIG. 2, replacement cards for the discarded cards of firstHAND 71 are displayed and the final first HAND 71 has a poker handcombination of a Full House. Additional cards are displayed into secondHAND 72 and the final second HAND 72 has a poker hand combination of aPair of Aces. Additional cards are displayed into third HAND 73 and thefinal third HAND 73 has a poker hand combination of Four Aces.

A pay table is displayed to the player showing the amounts that theplayer can win based on the poker hand ranking achieved by the playerand the amount wagered by the player.

In the example shown in FIGS. 1 and 2, a Jacks or Better draw poker gameformat is used. A suitable pay table for this format would be:

TABLE 1 DRAW POKER NUMBER OF COINS BET POKER HAND 1 2 3 4 5 ROYAL FLUSH250 500 750 1000 4000 STRAIGHT FLUSH 50 100 150 200 250 FOUR-OF-A-KIND25 50 75 100 125 FULL HOUSE 9 18 27 36 45 FLUSH 6 12 18 24 30 STRAIGHT 48 12 16 20 THREE-OF-A-KIND 3 6 9 12 15 TWO PAIR 2 4 6 8 10 JACKS ORBETTER 1 2 3 4 5

Using the pay table shown in Table 1, final HAND 71 is a winningcombination of a Full House and the player would receive forty-fivecredits as a payout based on the 1× multiplier 61. Final HAND 72 is awinning combination of Jacks or Better and the player would receive fivecredits as a payout based on the 1× multiplier 62. Final HAND 73 is awinning combination of Four-of-a-Kind and the player would receive onehundred twenty-five credits as a payout based on the 1× multiplier 63.

The multipliers to be applied to each hand in round two of the game arealso determined based on the outcome of each hand in the first round.The multipliers are based on the various poker hand categories that aredesignated as winning hand combinations for the poker format being used.A multiplier table is used and could be displayed to the player on thevideo screen display 20, on a second screen display or printed on theglass of the gaming machine. Any suitable multiplier table could beused. An exemplary multiplier table is shown in Table 2.

TABLE 2 ROYAL FLUSH 10×  STRAIGHT FLUSH 10×  FOUR-OF-A-KIND 10×  FULLHOUSE 6× FLUSH 6× STRAIGHT 5× THREE-OF-A-KIND 4× TWO PAIR 4× JACKS ORBETTER 2×

Using the multiplier table shown in Table 2, the winning outcome for apoker hand category of a Full House in HAND ONE 71 results in a 6×multiplier shown at 161 in FIG. 3 and applied to HAND ONE 171 in thenext round of play. Likewise, the winning outcome for a poker handcategory of Jacks or Better in HAND TWO 72 results in a 2× multipliershown at 162 in FIG. 3 and applied to HAND TWO 172 in the next round ofplay. The winning outcome for a poker hand category of Four-of-a-Kind inHAND THREE 73 results in a 10× multiplier shown at 163 in FIG. 3 andapplied to HAND THREE 173 in the next round of play.

When the next round of play is conducted, the player would again make awager of thirty credits and a round of video poker would be played. Bymaking this thirty credit wager, the player is activating the multiplierfeature for the next round of play. As the example in FIG. 3 shows, theplayer achieved a losing outcome in HAND ONE 171 so the multiplierfeature reverts to 1× as shown in FIG. 4 at 261 for HAND ONE 271. Theplayer achieved a winning outcome for a poker hand category of aStraight in HAND TWO 162 so the multiplier feature shows a 5× multiplieras shown in FIG. 4 at 262 for HAND TWO 272. Also, the player achieved alosing outcome in HAND THREE 173 so the multiplier feature reverts to 1×as shown in FIG. 4 at 263 for HAND THREE 273.

This progression of multipliers continues from round to round as long asthe player continues to make the wager for the multiplier feature in theembodiment of the present invention which requires that the player makea wager to activate the multiplier feature.

Whenever the player achieves a losing hand combination on any hand ofplay, then the next hand of play would be played at the normal 1×payout.

While the examples shown in FIGS. 1 through 4 use a regular Jacks orBetter draw poker format pay table, other pay tables have been developedfor the other variations of draw poker, such as Deuces Wild Poker, BonusPoker, Double Bonus Poker, Double Double Bonus Poker, Triple BonusPoker, Joker's Wild Poker or any of the myriad of video poker formatsthat have been developed. Each of these video poker formats uses variousarrangements of poker hand rankings as winning combinations and they usevarious payout amounts for the poker hand rankings. The amounts paid forthe various winning hand combinations in each of the video poker formatsare calculated to provide a certain theoretical game return based on themathematical probability of achieving the winning hand combinations andthe theoretical hold percentage that the casino wishes to offer to theplayers.

The method of the present invention can be applied to any of the variousvideo poker formats that are available or can be created for use.

The multipliers for a poker hand category can also be varied as desiredand can be applied to some or all of the poker hand categories that arewinning hand combinations for the poker format being used.

While the example given above has been described in connection with athree hand video poker game, the present invention can also be appliedto a single hand video poker game, or to any number of multiple handvideo poker games.

The present invention can also be applied to stud poker games, kenogames and slot machine games or any other casino game that uses a paytable.

The present invention has been described above in connection with amultiple hand draw poker game with the example using a three hand pokergame. However, the multiplier feature of the present invention can alsobe used in single hand or single reel games or in any game that has twoor more hands or reels.

In an embodiment, a method of playing a slot machine game in which aplayer can achieve modified awards on a next round of play comprises ona first round of play, providing a pay table with at least a first awardfor at least one winning symbol combination category. In an embodiment,there would be two or more winning symbol categories each having anaward associated therewith.

The gaming machine then randomly selects and displays at least a firstpay line of at least two symbols. In an embodiment, there would be twoor more pay lines that the player could choose to wager on and each payline would have more than two symbols. In an embodiment, there would bemultiple reels with each reel having multiple symbols. the pay lineswould include all or part of each reel.
